4. On which of the days minimum number of bulbs were sold?
5. If one big carton can hold 9 bulbs. How many cartons were needed in the given week?

Answer 1

(a) Number of bulbs sold on Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday are $12, 16, 8, 10, 14, 8$, and $18$ respectively.
(b) The maximum numbers of bulbs (i.e., $18$) were sold on Sunday.
(c) Equal numbers of bulbs (i.e., $8$) were sold on Wednesday and Saturday.
(d) The minimum numbers of bulbs (i.e., $8$) were sold on Wednesday and Saturday.
(e) Total bulbs sold in the week = $12 + 16 + 8 + 10 + 14 + 8 + 18 = 86$
Since one big carton can hold 9 bulbs, we would require
⇒ $\frac{86}{9}$ ≈ 10 cartons
∴ 10 cartons were needed in the given week.
